scription and dented (have it, titties r aim Mal 1 Application-filed February 23, 1922. serial No. teaser.

To all whom it may concern: Be it known that I, i-l osnrrr F. llmrrunonr, a citizen of the United Eitates, and a resident of La (trance, in the county at l roup and titate of seem-5a, have invented certain new and useiul Improvements in litotel iniite t iupports, ofv which the following is a speci- .lication,

lo. the usual type oit cotton cards, particularly ot the revolving; flat top type, the mote knives or card grids are approximately :torty inches in length and are small in cross section. Unless properly supported these knives flex easily, and any such tleirure is detrimental. toithe operation of the machine.

An. object of my inventionis to provide supporting means :tor mote knives that will prevent any tlexure and hold the knives iirmly in any position. to which they may be set.

Another object is to provide su iportinp; means that will prevent any vibration of the knives that might otherwise cause them to come into contact with the liclrer-in or the material thereon, and cause considerable damage.

it further object of the invention is to provide supporting means that is capable of minute and exact adjustment, but through simple devices can be easily set in. any desired position.

Further objects of the invention will be apparent from the following detailed dethe appended claims. in the drawings:

Figure l is a perspective view of parts ot a card showing my invention in its relation to the other parts,

Figure 2 is perspective view of the brace. Figure 1s a sectional NIGW on the line 23-43 of Figure l.

Figure 4t is a sectional view on the line l l: of Figure 3.

it frame A eta conventional. form of card is provided with a licker-in E and a bracket t for the mote knives l). The bracket is supported at its ends by arms it bolted to the frame A at F. These arms have oft-sets F through which pass adjusting; screws G for the mote knives. These parts are old and common and form no part of my invention except in combination with other features.

I provide a brace 1 of the general term shown in Figure-Z, which has a downturned end 2 provided with an elongated slot 3 through which passes a bolt l by means of which the brace is adjustably fastened to the itrame ot the card it. as shown in Figure 1.. This provides means for an up and down adjustment oi? the brace.

At about its middle, the bracket C has an otl'set lug 6 and the end oil the brace has an elongated slot This end of the brace is adapted to lie against the side ot the lug G" and a bolt 6 with nut 'Z adjustably connects the brace to the lug and thereby to the bracket i]. 'lhrougrh this adjustment the bracket "U with mote knives can be held at its desired position with relation to the licker-in.

At a slight distance tron], the slot 5 the brace is provided with an ear 8., preferably integral therwvith, into and through which threaded a screw 9. One end of this screw is adapted to bear against the offset lug (5, clearly illustrated in Figure 3. lit is ob vious that a very enact adjustniient can be obtained by loosening: the nut 7, turning the screw .9 to the desired degree, holding the lug G4 firmly against the screw, and tight ening the nut 7.

tlhis supporting: brace also permits the center oi the mote knife bracket to be raised or lowered slightly by n eons ot the bolt and slot connection l: and 3. lit is evident that any desired adjustment may be obtained and that the center of the bracket C may be held firmly so that it will be straight and no sap up; or vibration oil? the mote knives will be permitted. Any desired readjustment can be quickly made without any ditficulty and the parts retained in their new position. The adjustments permitted by the brace together with the adjustment oi the knives through the screws G enable the knives. to be set and held in the exact position. desired,

While it have shown and described the preterred term oi my device, it is obvious that certain changes may be made in term. and position without departing from the spirit of the invention as set forth in the claims,

it claim as my invention:

1. it mote lrni'te support comprising a bracket for the mote knives, a central lap; on said bracket, abrace member having a horizontal pin and slot connection at one end with the hip; and a vertical pin and slot connection at the other end with the frame of the machine, and means :tor holdin any desired the bracket in adjusted position, and means for holding the brace 1n adjusted position.

3. A mote knife support comprising a bracket for the mote knives supported at its ends on the machine frame, a brace member engaging the central portion of the bracket, an adjustable connection therebetween, means for holding the bracket in adjusted position and means for conneeting the brace to the frame of the machine.

4. A mote knife support comprising ab'racket for the mote knives, means for adjusting, the knives'in said bracket, a. brace engaging the central portion of the bracket,

means adjustably connecting the brace and bracket, and means adjustably connecting the brace and machine frame.

5. A mote knife support comprising a. bracket for the mote knives, means for adjusting the knives in thebracket, and a brace connecting the central portion of the bracketand machine frame and providing means'for adjustments of the bracket in vertical and transverse horizontal planes 6. A mote knife support comprisinga bracket for the mote knife, means connecting the ends of the bracket with the mav chine frame, a brace connecting the central portion of the bracket with the machine frame, and providing, means for adjustments of the bracket in a vertical plane and tion of the brace and machine frame permittinp; vertical adjustment of the brace.

8. In a mote knife support comprising: a bracket, a brace having a horizontal portion with a slot therein for adjustable attaehment to said bracket, and a dmxnturned end with a slot therein for adjustable attachment to the machine frame.

9. In a mote knife support comprising a bracket, a brace having a horizontal portion with a horizontal slot therein for :uljustable attachment to said bracket, and a downturned end with a vertical slot therein for adjustable attzn'hulent to the machine frame.

10. In a mote knife support comprising a bracket, a brace having a horizontal portion with a slot therein for adjustable attachment to said bracket and a lug adjacent thereto and carrying a set screw, and a downturned end with a vertical slot therein for adjustable attachment to the nlachine frame.

In testimony whereof I have hereunto subscribed my name.
